RULE 1401. NEW SOURCE REVIEW OF TOXIC AIR CONTAMINANTS

(a) Purpose

This rule specifies limits for maximum individual cancer risk (MICR), cancer

burden, and noncancer acute and chronic hazard index (HI) from new permit units,

relocations, or modifications to existing permit units which emit toxic air

contaminants listed in Table I. The rule establishes allowable risks for permit units

requiring new permits pursuant to Rules 201 or 203.

(b) Applicability

(1) Applications for new, relocated, and modified permit units which were

received by the District on or after June 1, 1990 shall be subject to Rule

1401. Applications shall be subject to the version of Rule 1401 that is in

effect at the time the application is deemed complete. Permit units installed

without a required permit to construct shall be subject to this rule, if the

application for a permit to operate such equipment was submitted after June

1, 1990.

(2) This rule shall apply to new, relocated, and modified equipment identified

in Rule 219 as not requiring a written permit if the risk from the equipment

will be greater than identified in subparagraph (d)(1)(A), or paragraphs

(d)(2) or (d)(3) in Rule 1401.

(c) Definitions

(1) ACCEPTABLE STACK HEIGHT for a permit unit is defined as a stack

height that does not exceed two and one half times the height of the permit

unit or two and one half times the height of the building housing the permit

unit, and shall not be greater than 65 meters (213 feet), unless the applicant

demonstrates to the satisfaction of the Executive Officer that a greater

height is necessary.

Rule 1401 (cont.) (Amended September 1, 2017)

1401 - 2

(2) BEST AVAILABLE CONTROL TECHNOLOGY FOR TOXICS

(T-BACT) means the most stringent emissions limitation or control

technique which:

(A) has been achieved in practice for such permit unit category or class

of source; or

(B) is any other emissions limitation or control technique, including

process and equipment changes of basic and control equipment,

found by the Executive Officer to be technologically feasible for

such class or category of sources, or for a specific source.

(3) CANCER BURDEN means the estimated increase in the occurrence of

cancer cases in a population subject to a MICR of greater than or equal to

one in one million (1.0 x 10-6) resulting from exposure to toxic air

contaminants.

(4) CONTEMPORANEOUS RISK REDUCTION means any reduction in risk

resulting from a decrease in emissions of toxic air contaminants at the

facility that is permanent, real, quantifiable and enforceable through District

permit conditions. Permit applications associated with the increase and

decrease in risk must be submitted together and the reduction of risk must

occur before the start of operation of the permit unit that will have an

increased risk. A contemporaneous risk reduction shall be calculated based

on the actual average annual emissions, as determined by facility records,

and annual emissions declarations pursuant to Rule 301 as appropriate, or

other data approved by the Executive Officer, whichever is less, which have

occurred during the two-year period immediately preceding the date of

application.

(5) FACILITY means any permit unit or grouping of permit units or other air

contaminant-emitting activities which are located on one or more

contiguous properties within the District, in actual physical contact or

separated solely by a public roadway or other public right-of-way, and are

owned or operated by the same person (or by persons under common

control), or an outer continental shelf (OCS) source as determined in 40

CFR Section 55.2. Such above-described groupings, if noncontiguous, but

connected only by land carrying a pipeline, shall not be considered one

facility. Notwithstanding the above, sources or installations involved in

crude oil and gas production in Southern California Coastal or OCS Waters

and transport of such crude oil and gas in Southern California Coastal or


1401 - 3

OCS Waters shall be included in the same facility which is under the same

ownership or use entitlement as the crude oil and gas production facility on-

shore.

(6) INDIVIDUAL SUBSTANCE ACUTE HAZARD INDEX (HI) is the ratio

of the estimated maximum one-hour concentration of a toxic air

contaminant for a potential maximally exposed individual to its acute

reference exposure level.

(7) INDIVIDUAL SUBSTANCE CHRONIC HAZARD INDEX (HI) is the

ratio of the estimated long-term level of exposure to a toxic air contaminant

for a potential maximally exposed individual to its chronic reference

exposure level. The chronic hazard index calculations shall include

multipathway consideration, if applicable.

(8) MAXIMUM INDIVIDUAL CANCER RISK (MICR) is the estimated

probability of a potential maximally exposed individual contracting cancer

as a result of exposure to toxic air contaminants for residential receptor

locations calculated pursuant to the Risk Assessment Procedures referenced

in subdivision (e). The MICR for worker receptor locations shall be

calculated pursuant to the Risk Assessment Procedures referenced in

subdivision (e). The MICR calculations shall include multipathway

consideration, if applicable.

(9) MODIFICATION means any physical change in, change in method of

operation, or addition to an existing permit unit that requires an application

for a permit to construct and/or operate. Routine maintenance and/or repair

shall not be considered a physical change. A change in the method of

operation of equipment, unless previously limited by an enforceable permit

condition, shall not include:

(A) an increase in the production rate, unless such increase will cause the

maximum design capacity of the equipment to be exceeded; or

(B) an increase in the hours of operation; or

(C) a change in ownership of a source; or

(D) a change in formulation of the materials processed which will not

result in a net increase of the MICR, cancer burden, or chronic or

acute HI from the associated permit unit.

For facilities that have been issued a facility permit pursuant to Regulation

XX or a Title V permit pursuant to Regulation XXX, modification means

any physical change in, change in method of operation of, or addition to an


1401 - 4

existing individual article, machine, equipment or other contrivance which

would have required an application for a permit to construct and/or operate,

were the unit not covered under a facility permit or Title V permit.

(10) PERMIT UNIT means any article, machine, equipment, or other

contrivance, or combination thereof, which may cause or control the

issuance of air contaminants, and which requires a written permit pursuant

to Rules 201 and/or 203. For facilities that have been issued a facility

permit or Title V permit, a permit unit for the purpose of this rule means

any individual article, machine, equipment or other contrivance which may

cause or control the issuance of air contaminants and which would require

a written permit pursuant to Rules 201 and/or 203 if it was not covered

under a facility permit or Title V permit. For publicly-owned sewage

treatment operations, each process within multi-process permit units at the

facility shall be considered a separate permit unit for purposes of this rule.

(11) RECEPTOR LOCATION means

(A) for the purpose of calculating acute HI, any location outside the

boundaries of the facility at which a person could experience acute

exposure; and

(B) for the purpose of calculating chronic HI and MICR, any location

outside the boundaries of the facility at which a person could

experience chronic exposure.

The Executive Officer shall consider the potential for exposure in

determining whether the location will be considered a receptor location.

(12) RELOCATION means the removal of an existing permit unit from one

parcel of land in the District and installation at another parcel of land where

two parcels are not in actual physical contact and are not separated solely

by a public roadway or other public right-of-way. The removal of a permit

unit from one location within a facility and installation at another location

within the facility is a relocation only if an increase in maximum individual

cancer risk in excess of one in one million (1.0 x 10-6) or a Hazard Index of

1.0 occurs at any receptor location.

(13) TOTAL ACUTE HAZARD INDEX (HI) is the sum of the individual

substance acute HIs for all toxic air contaminants affecting the same target

organ system.


1401 - 5

(14) TOTAL CHRONIC HAZARD INDEX (HI) is the sum of the individual

substance chronic HIs for all toxic air contaminants affecting the same

target organ system.

(15) TOXIC AIR CONTAMINANT is an air pollutant which may cause or

contribute to an increase in mortality or serious illness, or which may pose

a present or potential hazard to human health. For the purpose of this rule,

toxic air contaminants are those listed in Table I.

(d) Requirements

The Executive Officer shall deny the permit to construct a new, relocated or

modified permit unit if emissions of any toxic air contaminant listed in Table I may

occur, unless the applicant has substantiated to the satisfaction of the Executive

Officer all of the following:

(1) MICR and Cancer Burden

The cumulative increase in MICR which is the sum of the calculated MICR

values for all toxic air contaminants emitted from the new, relocated or

modified permit unit will not result in any of the following:

(A) an increased MICR greater than one in one million (1.0 x 10-6) at

any receptor location, if the permit unit is constructed without T-

BACT;

(B) an increased MICR greater than ten in one million (10 x 10-6) at any

receptor location, if the permit unit is constructed with T-BACT;

(C) a cancer burden greater than 0.5.

(2) Chronic Hazard Index

The cumulative increase in total chronic HI for any target organ system due

to total emissions from the new, relocated or modified permit unit owned

or operated by the applicant for which applications were deemed complete

on or after the date when the risk value for the compound is finalized by the

state Office of Environmental Health Hazard Assessment (OEHHA) will

not exceed 1.0 at any receptor location.

(3) Acute Hazard Index

The cumulative increase in total acute HI for any target organ system due

to total emissions from the new, relocated or modified permit unit owned

or operated by the applicant for which applications were deemed complete

on or after the date when the risk value for the compound is finalized by

OEHHA will not exceed 1.0 at any receptor location.


1401 - 6

(4) If a permit contains operating conditions imposed pursuant to Rule 1401,

which prohibit or limit the use or emission of toxic air contaminants, those

conditions shall apply only to those toxic air contaminants listed in the

version of Rule 1401 applicable at the time the permit conditions were

imposed.

(5) Federal New Source Review for Toxics

Pursuant to Section 112(g) of the federal Clean Air Act (CAA), no person

shall begin construction or reconstruction of a major stationary source

emitting hazardous air pollutants listed in Section 112 (b) of the CAA,

unless the source is constructed with Best Available Control Technology

for Toxics (T-BACT) and complies with all other applicable requirements,

including definitions and public noticing, referenced in 40 CFR 63.40

through 63.44. The requirements of this paragraph shall not apply to:

(A) any source that is subject to an existing National Emission Standard

for Hazardous Air Pollutants (NESHAP) pursuant to sections

112(d), 112(h), or 112(j) of the federal CAA;

(B) any source that is exempted from regulations under a NESHAP

issued pursuant to sections 112(d), 112(h), or 112(j) of the federal

CAA;

(C) any source that has received all necessary air quality permits for

such construction or reconstruction before June 29, 1998;

(D) electric utility steam generating units, unless and until such time as

these units are added to the source category list pursuant to the

requirements of section 112(c)(5) of the federal CAA;

(E) any sources that are within a source category that has been deleted

from the source category list pursuant to section 112(c)(9) of the

federal CAA; or

(F) research and development activities.

Compliance with this paragraph does not relieve any owner or operator of

a major stationary source from complying with all other applicable District

rules and regulations, including this rule, any applicable state airborne toxic

control measure, or other applicable state and federal laws. Exemptions

under subdivision (g) of this rule do not apply to this paragraph. This

paragraph shall take effect retroactively from June 29, 1998.


1401 - 7

(e) Risk Assessment Procedures

(1) The Executive Officer shall periodically publish procedures for

determining health risks under this rule. To the extent possible, the

procedures will be consistent with the most recently adopted policies and

procedures of the state OEHHA.

(2) To calculate the cumulative increase in MICR pursuant to paragraph (d)(1),

the increase from each permit unit shall be based on the emissions of toxic

air contaminants, the risk values, and risk assessment procedures applicable

at the time when each complete application was deemed complete by the

District.

(f) Emissions Calculations

(1) For the purpose of determining MICR and cancer burden due to a new or

relocated permit unit pursuant to this rule, the total Toxic Air Contaminant

emissions from the new or relocated permit unit shall be calculated on an

annual basis from permit conditions which directly limit the emissions or,

when no such conditions are imposed, from:

(A) the maximum rated capacity;

(B) the maximum possible annual hours of operation;

(C) the maximum annual emissions; and

(D) the physical characteristics of the materials processed.

(2) For the purpose of determining chronic HI due to a new or relocated permit

unit pursuant to this rule, the total emissions from a permit unit shall be

calculated on an annual average basis from permit conditions which directly

limit the emissions or, when no such conditions are imposed, from:


(B) the annual average hours of operation;

(C) the annual average emissions; and

(D) the physical characteristics of the materials processed.

(3) For the purpose of determining MICR, cancer burden and chronic HI due

to a modified permit unit pursuant to this rule, the increase in emissions

from the modified permit unit shall be calculated based on the difference

between the total permitted emissions after the modification, calculated

pursuant to the criteria established in subparagraphs (f)(1)(A), (B), (C), and

(D), and:


1401 - 8

(A) the total permitted emissions prior to the modification as stated in

the permit conditions; or

(B) if there are no existing permit conditions that limit emissions, the

average annual emissions which have occurred during the two-year

period immediately preceding the date of the complete permit

application for modification or other appropriate period determined

by the Executive Officer to be representative of a permit unit's

operation; or

(C) for modification of any source installed prior to October 8, 1976,

resulting from the addition of air pollution controls installed solely

to reduce the issuance of air contaminants, emission shall be

calculated from permit conditions which directly limit the emissions

or, when no such conditions are imposed, from:

(i) the maximum rated capacity; and

(ii) the maximum proposed daily hours of operation; and

(iii) the physical characteristics of the materials processed.

(4) For the purpose of determining acute HI due to a new, relocated or modified

permit unit pursuant to this rule, the total emissions from a permit unit shall

be calculated on a maximum hourly basis from permit conditions which

directly limit the emissions or, when no such conditions exist, from:


(B) the maximum hourly emissions; and

(C) the physical characteristics of the materials processed.

(5) De Minimus Values

Any permit unit with values at or below the screening levels as specified in

the procedures for determining health risks under this rule, published

pursuant to paragraph (e)(1), shall be deemed in compliance with the

requirements of subdivision (d).

(g) Exemptions

(1) The requirements of subdivision (d) shall not apply to:

(A) Permit Renewal or Change of Ownership

Any permit unit which is in continuous operation, without

modification or change in operating conditions, for which a new

permit to operate is required solely because of permit renewal or

change of ownership.


1401 - 9

(B) Modification with No Increase in Risk

A modification of a permit unit that causes a reduction or no

increase in the cancer burden, MICR or acute or chronic HI at any

receptor location.

(C) Functionally Identical Replacement

A permit unit replacing a functionally identical permit unit,

provided there is no increase in maximum rating or increase in

emissions of any toxic air contaminants. For replacement of dry

cleaning permit units only, provided there is no increase in any toxic

air contaminants.

(D) Equipment Previously Exempt Under Rule 219

Equipment which previously did not require a written permit

pursuant to Rule 219 that is no longer exempt, provided that the

equipment was installed prior to the Rule 219 amendment

eliminating the exemption and a complete application for the permit

is received within one (1) year after the Rule 219 amendment

removing the exemption.

(E) Modifications to Terminate Research Projects

Modifications restoring the previous permit conditions of a permit

unit, provided that: the applicant demonstrates that the previous

permit conditions were modified solely for the purpose of installing

innovative control equipment as part of a demonstration or

investigation designed to advance the state of the art with regard to

controlling emissions of toxic air contaminants; the emission

reductions achieved by the demonstration project are not used for

permitting any equipment with emission increases under the

contemporaneous emission reduction exemption as specified in

paragraph (g)(2); the demonstration project is completed within two

(2) years; and a complete application is submitted no later than two

(2) years after the date of issuance of the permit which modified the

conditions of the previous permit for the purpose of the

demonstration or investigation.

(F) Emergency Internal Combustion Engines

Emergency internal combustion engines that are exempted under

Rule 1304.

(G) Wood Product Stripping


1401 - 10

Wood product stripping permit units, provided that the risk

increases due to emissions from the permit unit owned or operated

by the applicant for which complete applications were submitted on

or after July 10, 1998 will not exceed a MICR of 100 in one million

(100 x 10-6

) or a total acute or chronic hazard index of five (5) at

any receptor location. This exemption shall not apply to permit

applications received after January 10, 2000, or sooner if the

Executive Officer makes a determination that T-BACT is available

to enable compliance with the requirements of paragraphs (d)(1),

(d)(2) and (d)(3).

(H) Gasoline Transfer and Dispensing Facilities

For gasoline transfer and dispensing facilities, as defined in Rule

461 – Gasoline Transfer and Dispensing, the Executive Officer shall

not, for the purposes of paragraphs (d)(1) through (d)(4), consider

the risk contribution of methyl tert-butyl ether for any gasoline

transfer and dispensing permit applications deemed complete on or

before December 31, 2003. If the state of California extends the

phase-out requirement for methyl tert-butyl ether as an oxygenate

in gasoline, the limited time exemption shall be extended to that

expiration date or December 31, 2004, whichever is sooner.

(2) Contemporaneous Risk Reduction

(A) Paragraph (d)(1) shall not apply if the applicant demonstrates that a

contemporaneous risk reduction resulting in a decrease in emissions

will occur such that both of the following conditions are met:

(i) no receptor location will experience a total increase in

MICR of greater than one in one million (1.0 x 10-6

) due

to the cumulative impact of both the permit unit and the

contemporaneous risk reduction; and

(ii) the contemporaneous risk reduction occurs within 100

meters of the permit unit.

T-BACT shall be used on permit units exempted under this

subparagraph if the MICR from the permit unit exceeds one in one

million (1.0 x 10-6).

(B) The requirements of paragraphs (d)(2) and (d)(3) shall not apply if

the applicant substantiates to the satisfaction of the Executive

Officer that a contemporaneous risk reduction will occur such that


1401 - 11

any increase in individual substance acute or chronic HI from the

permit unit exceeding 1.0 is mitigated with an equal or greater

decrease in the same individual substance acute or chronic HI,

respectively, from the contemporaneous risk reduction such that

both of the following conditions are met:

(i) no receptor location will experience an increase in total

acute or chronic HI of more than 1.0 due to the cumulative

impact of both the permit unit and the contemporaneous

risk reduction; and

(ii) the contemporaneous risk reduction occurs within 100

meters of the permit unit.

(3) Alternate Hazard Index Levels

The requirements of paragraphs (d)(2) and (d)(3) shall not apply if the

applicant substantiates to the satisfaction of the Executive Officer that at all

receptor locations and for every target organ system, the total chronic and

acute HI level resulting from emissions from the new, modified or relocated

permit unit owned or operated by the applicant for which applications were

submitted on or after July 10, 1998 shall not exceed alternate HI levels

which are determined by the Executive Officer in consultation with the

Office of Environmental Health Hazard Assessment to be protective against

adverse health effects. No alternate HI level shall exceed 10.
